To all whom it may concern v Be it mover: that I, Emvaeo G. Mars, acitizen of the United States, residing at Wih mington, in the county ofNew Castle andfor use in loose-leaf filing or index card or leafsystems, the primary object of the invention being to provide a devicefor reinforcing and protecting the index tab on partition cards, so asto prevent the same from being bent, frayed or torn from strain inhandling, or contact with the other ele ments of the system.

A. further object of the invention is to provide an index card or sheetreinforcing device which may be conveniently applied to any type ofpartition or index card so as to reinforce the tab and adjacent portionof the card and which may bearranged to hold the tab at an angle so asto maintain the cards or sheets properly spaced and sustained, While atthe same time disposing the index character on the card so as to be moreconveniently viewed.

A further object of the invention is to pro vide a reinforcing device ofthe character described which admits of the insertion and retention ofships to change the index character of the card, and which, Whennsed generaily throughout the system, will sustain and brace the cards or sheetsof the system in a desirable manner. I

The invention consists of the features of construction, combination andarran ernent of parts herein fully described and c aimed.

Figure l is asectional perspective view of an index or file drawer,showing one of the reinforcin devices applied to a card or sheettherein. ig. 2 is a vertical section through the device and portion ofthe card engaged thereby. Fig. 3 is a perspective view of the devicedetached. Fig. 4: is a perspective view of a modined form of reinforcingde vice. Fig. 5 is a similar view of still another modified iorni ofreinforcing device.

Referring to the drawing, '1 design ates the file or index card or sheetprovided with the usual extension tab 2, on Which is Written or printedthe index character. The reinforcing and protecting device 8 is appliedto this tab and the adjacent portion of the card or sheet, and consistsof a folded or doubled piece of sheet metal made from specification oiLetters Patent.

Thisdevice comprises a pair of members or jaws l and 5, united at t outer orupper edges by the hight or fol "1d portion 6, said jaws being rcterablyef loblong rectangular form and of safiiciefitdi mansions to receive andcon- 11 th tel? 9 between them,

In practice, the device is slipped down over upon the tab 2 andadjacent'marginal .5 portion of the tab or sheet 1, so as to the tab 2,and for the purpose o strengthen. mg and reinforcing the adjacentnortnmfif; the card or sheet the jaivsare-providcd wiiih' 76 anysuitable term. 'ihese arms, or eaten,

sions also form fastening means, one of said arms or extensions beingprovided with, one" or more openings 9 to receive a correspond,- ingnumber of tongues 10 struck up frog the other arm, which tongueortonguesare; passed through the material ofthe (larder; sheet and through theopeningfor oieenings" 9 and then bent or clenched against the'outer faceof the jaw i to firmly fasten the device 1 in position. 1 i The jaw t istermed with. an ohservatr opening 11 therein to expose the ind jaws iand 5 are bent rearwardly oblique angle of: inclination, so that theindextab will be held in a position ferreterence, and it will be evidentthat by hand ing said jaws at different angles relative to the fasteningarms 7 and 8 the angled? in- 9 c'lination of the tab may becorrespondingly varied. The jaws not only hold the tab rigid, andprotect the same from being torn, frayed or broken, but also permit oftheintroduction of a sh? hearing 'difierent in-j g dex character betweenthe indihntab and jaiv' i, so that the index character may changed whendesired. The arms 7 and 8 also reinforce the body of the card or sheetatpoints adjacent the tab, thus adefiting 1 0 the partition card toWithstand the strains from handling and pressure from the index cards orsheets to a greater degree,'as will be readily understood. The devicealso provides a stiffened linger piece by which the- 5 partition card orsheet may be more con-' veniently manipulated.

The invention may be modified in many respects. As shown in Fig. i, thearms 7 and 8 may he lengthened to provide exteniw sions '2" and 8depending to any desired extent throughout the length of the partitionpensed with,

card or sheet, thus reinforcing the latter to agreater degree. Also, asshown in Fig. 5, the openings 9 and tongues 10 may be disand tongues 12provided along the lateral margins of one of the arms 7 which areadapted to be passed through the partition card and bent over upon theother arm 8" to hold the device' fastened' to'the partition card. Fromthe foregoing connection with the drawings,

description, taken in it will be seen that'my invention provides adevice for reinmeans, one of said jaws having an opening therein toexpose the index character card.

on the ,2; A reinforcing and protecting device for indexv cards,comprising a piece of sheet material folded to provide a pair of jaws toreceive'the index tab, and arms adapted to bear upon the opposite sidesof. the card and having means of attachment thereto, said jaws beingbent at an angle of inclination to said arms, one of said jaws beingformed with an opening therein'to expose the index character on the tab.

3. A reinforcing and protecting device for index cards, material bent toadapted to lie on opposite sides of the card, one at least of said armsbeing provided with integral means for attaching said arms to the card,the said jaws having their upper 1 portions bent at an angle to theplane of the arms and one of said jaws having an open ing therein toexpose the index character on the tab.

In testimony whereof I afiix my signature in presence of two witnesses.
